Microsoft is rolling out a second tech preview of Visual Studio 2013 Update 2 on February 25 -- one with support for its new TypeScript language and tooling built in.
Visual Studio 2013 Update 2 Community Technology Preview (CTP) 2 includes the near-final release candidate of TypeScript 1.0 "in the box." (The TypeScript 1.0 Release Candidate also is available for Visual Studio 2012 customers as a standalone installer.)
Microsoft officials said the final release of TypeScript 1.0 will be part of the final release of Visual Studio 2013 Update 2. They aren't pinning a target delivery date on when Update 2 will be final, but given the rapid pace at which the team has been rolling out Visual Studio updates, it probably won't be long.
Hejlsberg called TypeScript one of Microsoft first big forays into open source from the get-go of the project. (It's available under an Apache 2.0 license.)
As of CTP2 of Visual Studio Update 2, TypeScript officially becomes a "first-class language in Visual Studio," Hejlsberg said. "It will be in Visual Studio proper, as opposed to a separate download."
Hejlsberg said he has been surprised himself about the adoption of TypeScript since its announcement, both internally at Microsoft and externally. Microsoft's browser-based development toolbox, codenamed "Monaco," was developed using TypeScript. The new UI in Xbox Music, various Bing projects, the F12 tools in Internet Explorer and Adobe's Digital Publishing Suite also were all written using TypeScript, Hejlsberg said.

The CTP 2 build is cumulative and includes everything already released in CTP 1 for Visual Studio 2013 Update 2.
